1. Brockville Brackets (BB) has a three-year-old robot that welds small brackets onto carframe assemblies. At the time the robot was purchased, it cost $300 000 and an additional $50 000 was spent on installation. BB acquired the robot as part of an eight-year contract to produce the car-frame assemblies. The useful life of the robot is 12 years, and its value is estimated to decline by 20 percent of the current value per year, as shown in the first table below. Operating and maintenance costs estimated when the robot was purchased are also shown in the table. BB has found that the operating and maintenance costs for the robot have been higher than anticipated. At the end of the third year, new estimates of the operating and maintenance costs are shown in the second table on the next page. BB has determined that the reason the operating and maintenance costs were in error was that the robot was positioned too close to existing equipment for the mechanics to repair it easily and quickly. BB is considering moving the robot farther away from some adjacent equipment so that mechanics can get easier access for repairs. To move the robot will cause BB to lose valuable production time, which is estimated to have a cost of $25 000. However, once complete, the move will lower maintenance costs to what had originally been expected for the remainder of the contract (e.g., $40 000 for the fourth year, increasing by 10 percent per year thereafter). Moving the robot will not affect its salvage value.1. Brockville Brackets (BB) has a three-year-old robot that welds small brackets onto carframe assemblies.

If BB Uses a MARR of 15 Percent, Should it more the robot ? If So, when ? Remember that the contract exists only for a further five years.
